1 A student carries out an experiment to investigate the relationship between the

sine of the angle of incidence, iand the sine of the angle of refraction, rof a glass

block.

The arrangement of the apparatus for the experiment is shown in Figure 1.1

Seorang pelajar menjalankan eksperimen untuk mengkaji hubungan di antara sin sudut tuju,i dan

sin sudut biasan,r bagi suatu blok kaca.

Susunan alat radas eksperimen seperti yang ditunjukkan pada Rajah 1.

A ray of light is directed along the angle of incidence,i= 20oand forms the angle

of refraction, r. The angle of refraction is measured by using a protractor. The

corresponding reading ofr1, is shown in Figure 1.2 on page 5.

The experiment is repeated by varying the angle of incidence, i, to 30o, 40

o, 50

o

and 60o. The corresponding angles of refraction, rare shown in Figures 1.3, 1.4,

1.5 and 1.6 on pages 6 and 7 respectively.

Satu sinar cahaya ditujukan ke bongkah kaca pada sudut tuju, i = 20o dan membentuk sudut

biasan, r. Sudut biasan diukur dengan menggunakan protrektor. Bacaan sudut biasan, r1 yang

sepadan ditunjukkan pada Rajah 1.2 pada halaman 5.

Eksperimen ini diulangi dengan mengubah sudut tuju, i , kepada 30o , 40o , 50o dan 60o. Bacaan

bagi sudut biasan, ryang sepadan ditunjukkan pada Rajah 1.3, 1.4, 1.5 dan 1.6 pada halaman 6
